Answer:
K_{total} = 19.4 J
Explanation:
The total kinetic energy that is formed by the linear part and the rotational part is requested
let's look for each energy
linear
= ½ m v²
rotation
= ½ I w²
the moment of inertia of a solid sphere is
I = 2/5 m r²
we substitute
= ½ mv² + ½ I w²
angular and linear velocity are related
v = w r
we substitute
K_{total} = ½ m w² r² + ½ (2/5 m r²) w²
K_{total} = m w² r² (½ + 1/5)
K_{total} = 
m w² r²
let's calculate
K_{total} = 6.40 16.0² 0.130²
K_{total} = 19.4 J

Explanation:
The question is incomplete. To get the voltage V across the resistors, we need to total current flowing in the circuit.
Let the current I = 6 A
According to ohms law, V = IRt
V is the total voltage
I is the total current
Rr is the total effective resistance
Since the 2 4ohms resistors are connected in parallel;
1/Rt = 1/4 + 1/4
1/Rt = 2/4
Cross multiply
2Rt = 4
Rt = 4/2
Rt = 2 ohms
Get the voltage V.
V = IRt
V = 6(2)
V = 12V
Hence the required voltage will be 12V
<em>Note that the value of the current used was assumed. The same calculation can be employed for any value of the current</em>
Answer: Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes
Explanation:
Answer:a means of solving a problem or dealing with a difficult situation.
Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.
